WebbWe will construct a Bayesian model of simple linear regression, which uses Abdomen to predict the response variable Bodyfat. Let yi, i = 1, ⋯, 252 denote the measurements of the response variable Bodyfat, and let xi be the waist circumference measurements Abdomen. We regress Bodyfat on the predictor Abdomen. WebbRegression analysis is like any other inferential methodology. Our goal is to draw a random sample from a population and use it to estimate the properties of that population. In regression analysis, the coefficients in the equation are estimates of the actual population parameters.
